Abstract

The invention relates to an optical fiber-to-full configuration type Camera link real-time image optical transceiver based on an FPGA (Field Programmable Gate Array). The optical transceiver realizes the conversion function from optical fiber real-time image input to high-bandwidth (85 MHz) and high-reliability full configuration type Camera link real-time image output, has self-adaptive configuration functions of full configuration type, medium type or base type Camera link real-time image output and also realizes the conversion function from Camera link serial port data and timing synchronous control signal input to optical fiber data stream output, so that the communication distance between a Camera link serial port and a timing synchronous control signal is extended; through the design, the flexible configuration of an SFP optical fiber module is provided, the transmission distance is from 500 meters to 120 kilometers, the stability and the reliability of Camera link real-time image transmission are improved, the anti-electromagnetic interference ability of the Camera link SFP real-time image transmission is enhanced, and the demands on various engineering application occasions are met.

technical field [0001] The present invention relates to high-bandwidth (85MHz), high-reliability full-configuration (Full) Camera link real-time image long-distance transmission, in particular to a Camera link high-speed real-time image remote transmission based on FPGA (Field Programmable Gate Array, Field Programmable Gate Array) Distance transmission is realized. Background technique [0002] In the traditional camera link image transmission system, the transmission medium between devices is directly connected by camera link cable. Due to the poor anti-interference performance of the camera link cable and the short transmission distance (less than 10 meters), it cannot meet the requirements Long-distance transmission.

[0002] In the traditional camera link image transmission system, the transmission medium between devices is directly connected by camera link cable. Due to the poor anti-interference performance of the camera link cable and the short transmission distance (less than 10 meters), it cannot meet the requirements long-distance transmission

In recent years, with the development of optical fiber interconnection transmission technology, basic (Base) Camera link image optical transceivers based on optical fiber transmission have gradually appeared, but they can only realize basic (Base) Camera link image transmission, and the transmission distance is short (about 300 meters), which fail to meet the long-distance transmission of long-distance camera link real-time images with medium configuration (Medium), full configuration (Full), and high bandwidth (85MHz) for engineering needs, and fail to meet the transmission of longer distances (100 kilometers and above) need
